Abstract

The embodiment of the invention discloses a hot topic tracking and keyword determination method and device. A hot topic keyword determination method is to obtain hot topic data on a set website, and to determine hot topic keywords in time by performing word segmentation and clustering on these hot topic data; a hot topic tracking method is to target each hot topic Topics, according to the text similarity between keywords of the hot topics and the description information of the video files, the video files corresponding to the hot topics are tracked. Applying the technical solution provided by the embodiment of the present invention, the determination of hot topic keywords and hot topic tracking are all automatically completed by the server, which effectively avoids the lag problem caused by manual operation to determine hot topics, and even if a hot topic may Consisting of many phased events, the server can execute the technical solution multiple times, and the video files corresponding to the hot topic can be regularly updated, saving labor operation costs.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a hot topic tracking and keyword determination method and device. Background technique [0002] Hot topics refer to hot issues that are most concerned by the public within a certain period of time and within a certain range. In video websites, UGC (User Generated Content, user-generated content) videos are mostly released by users at the first time when hot events or topics occur, and have a certain timeliness.
